Gingival salivary gland choristoma: An unusual case report.

The gingival salivary gland choristoma, a highly unusual tumor-like mass alteration constituted by normal salivary gland cells in an abnormal location, reported for the first time in 1964 by Moskow and Baden. To our knowledge, only 12 cases of this entity (including present case) are reported to date, the majority observed as asymptomatic, solitary, smooth-surfaced tumor-like masses, measuring 0.5-1.
